| | ^^^^^^^^^^^^ read access through <TAG> at ALLOC[0x5] is forbidden |
| | |
| = help: this indicates a potential bug in the program: it performed an invalid operation, but the Tree Borrows rules it violated are still experimental |
| = help: the accessed tag <TAG> has state Disabled which forbids this child read access |
| help: the accessed tag <TAG> was created here, in the initial state Reserved |

| LL | let rmut = &mut *addr_of_mut!(data[0..6]); |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| help: the accessed tag <TAG> later transitioned to Disabled due to a foreign write access at offsets [0x5..0x6] |
| --> tests/fail/tree_borrows/error-range.rs:LL:CC |

| LL | data[5] = 1; |
| | ^^^^^^^^^^^ |
| = help: this transition corresponds to a loss of read permissions |
